The Simpson Strong-Tie AB200 Ready Trim Bender allows the user to curve angles quickly and accurately on the job site by creating compound indentations at consistent intervals along the length of the angle. It eliminates the need for old-fashioned tin snips and a trial-and-error method approximating the right radius. The tough heavy-gauge steel construction allows for smooth, trouble-free operation for each job. It is great for 20- to 25-gauge angles with 1 1/2" x 1 1/2", 2" x 2" or 3" x 3" legs. The minimum radius is 30" -44".
